I get these lines when printing most parts. I am using eSUN PLA+ at 205 °C (210 °C first layer) nozzle and 85 °C bed temps (it does not really want to stick below that on the stock build platform), but even then it came loose and the print failed. I sliced it with Cura 4.9 with retraction enabled. I tried readjusting the rollers for the Z-axis, calibrated the E-steps, I ran out of ideas. It is a new printer and I have not had a single "good" print with it yet. Any help would be much appreciated.
